A teenager allegedly involved in a sustained assault on a girl which was filmed and posted online has been attacked in custody and had his bed urinated on, the High Court heard today.

Counsel for the 18-year-old accused claimed he was targeted because of publicity surrounding the encounter on the pier at Bangor, Co Down.

Details emerged as he was refused bail amid allegations of defying a ban on entering the seaside town. The defendant cannot be named due to ongoing legal attempts to maintain reporting restrictions which applied before he turned 18, Belfast Live reports.

He faces charges of grievous bodily harm with intent and assault occasioning actual bodily harm to the 16-year-old girl. Cora Campbell, 18, of English Street in Downpatrick, and another 16-year-old girl have also been charged.
